Harrisburg, Pennsylvania in the context of "Pennsylvania"

A media market, broadcast market, media region, designated market area (DMA), television market area, or simply market, is a region where the population can receive the same (or similar) television and radio station offerings, and may also include other types of media such as newspapers and internet content. They can coincide with or overlap with one or more metropolitan areas, though rural regions with few significant population centers can also be designated as markets. Conversely, very large metropolitan areas can sometimes be subdivided into multiple segments. Market regions may overlap, meaning that people residing on the edge of one media market may be able to receive content from other nearby markets. They are widely used in audience measurements, which are compiled in the United States by Nielsen Media Research. Nielsen has measured both television and radio audiences since its acquisition of Arbitron, which was completed in September 2013.

Markets are identified by the largest city, which is usually located in the center of the market region. However, geography and the fact that some metropolitan areas have large cities separated by some distance can make markets have unusual shapes and result in two, three, or more names being used to identify a single region (such as Wichita–Hutchinson, Kansas; Chico–Redding, California; Albany–Schenectady–Troy, New York; and Harrisburg–Lebanon–Lancaster–York, Pennsylvania).

The Hagerstown–Martinsburg metropolitan area, officially designated by the United States Office of Management and Budget (OMB) as Hagerstown–Martinsburg, Maryland–West Virginia Metropolitan Statistical Area (MSA), constitutes the primary cities of Hagerstown, Maryland; Martinsburg, West Virginia; and surrounding areas in three counties: Washington County, Maryland; Berkeley County, West Virginia; and Morgan County, West Virginia. The metro area lies mainly within the rich, fertile Cumberland and Shenandoah Valleys and is approximately a 60–90 minute drive from Washington, D.C.; Baltimore, Maryland; and Harrisburg, Pennsylvania; Hagerstown is approximately 75 miles (121 km) driving distance from all three cities. The population of the metropolitan area as of 2008 is 263,753.

The Flight 93 National Memorial is a memorial built to commemorate the crash of United Airlines Flight 93, which was one of four aircraft hijacked during the September 11 attacks in 2001. The memorial is located in Somerset County, Pennsylvania, with the vast majority in Stonycreek Township, and with a small portion in Shade Township. It is 78 miles (126 km) southeast of Pittsburgh, 122 miles (196 km) west of Harrisburg (the state capital), and 226 miles (364 km) west of Philadelphia.

A national memorial was created to honor the passengers and crew of Flight 93, who stopped the terrorists from reaching their target by fighting the hijackers. A temporary memorial to the 40 victims was established soon after the crash. The first phase of the permanent memorial was completed, opened, and dedicated on September 10, 2011. The design for the memorial is a modified version of the entry Crescent of Embrace by Paul and Milena Murdoch.

A tholobate (from Ancient Greek θολοβάτης (tholobátēs) 'dome pedestal'), also called a drum or tambour, is the upright part of a building on which a dome is raised. It is generally in the shape of a cylinder or a polygonal prism. The name derives from the tholos, the Greek term for a round building with a roof and a circular wall. Another architectural meaning of drum is a circular section of a column shaft.

The Battle of Gettysburg (locally /ˈɡɛtɪsbɜːrɡ/ ) was a three-day battle in the American Civil War, which was fought between the Union and Confederate armies between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, won by the Union, is widely considered the Civil War's turning point, leading to an ultimate victory of the Union and the preservation of the nation. The Battle of Gettysburg was the bloodiest battle of both the Civil War and of any battle in American military history, claiming over 50,000 combined casualties. Union Major General George Meade's Army of the Potomac defeated attacks by Confederate General Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North and forcing his retreat.

After his success in the Battle of Chancellorsville in Spotsylvania County, Virginia in May 1863, Lee led his Confederate forces through Shenandoah Valley to begin the Gettysburg campaign, his second attempt to invade the North. With Lee's army in high spirits, he intended to shift the focus of the summer campaign from war-ravaged Northern Virginia in the hopes of penetrating as far as Harrisburg or Philadelphia, which he hoped would convince northern politicians to end the war. President Abraham Lincoln initially prodded Major General Joseph Hooker into pursuing Lee, then relieved him of command just three days before the Battle of Gettysburg commenced, replacing him with Meade.

The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station, located on the Susquehanna River in Londonderry Township, Dauphin County near Harrisburg, Pennsylvania. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the environment. It is the worst accident in U.S. commercial nuclear power plant history, although its small radioactive releases had no detectable health effects on plant workers or the public. On the seven-point logarithmic International Nuclear Event Scale, the TMI-2 reactor accident is rated Level 5, an "Accident with Wider Consequences".

The accident began with failures in the non-nuclear secondary system, followed by a stuck-open pilot-operated relief valve (PORV) in the primary system, which allowed large amounts of water to escape from the pressurized isolated coolant loop. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident (LOCA). TMI training and operating procedures left operators and management ill-prepared for the deteriorating situation caused by the LOCA. During the accident, those inadequacies were compounded by design flaws, such as poor control design, the use of multiple similar alarms, and a failure of the equipment to indicate either the coolant-inventory level or the position of the stuck-open PORV.

Western Pennsylvania is a region in the Commonwealth of Pennsylvania encompassing the western half of the state. Pittsburgh is the region's principal city, with a metropolitan area population of about 2.4 million people, and serves as its economic and cultural center. Erie, Altoona, and Johnstown are its other metropolitan centers. As of the 2020 census, Western Pennsylvania had a population of 3,753,944.

Although the Commonwealth does not designate Western Pennsylvania as an official region of the state, it has retained a distinct identity since the colonial-era Province of Pennsylvania because of its geographical distance from Philadelphia, the state's first settlement, and because of its topographical separation from eastern Pennsylvania, including the Appalachian Mountains, which characterizes the region. The strong cultural identity of Western Pennsylvania is reinforced by the state supreme court, which convenes in Pittsburgh in addition to Harrisburg and Philadelphia.

The Pennsylvania State Capitol is the seat of government for the U.S. state of Pennsylvania located in downtown Harrisburg. The building was designed by architect Joseph Miller Huston in 1902 and completed in 1906 in a Beaux-Arts style with decorative Renaissance themes throughout. The capitol houses the legislative chambers for the Pennsylvania General Assembly, made up of the House of Representatives and the Senate, and the Harrisburg chambers for the Supreme and Superior Courts of Pennsylvania, as well as the offices of the Governor and the Lieutenant Governor. It is also the main building of the Pennsylvania State Capitol Complex.

The seat of government for the state was initially in Philadelphia, then was relocated to Lancaster in 1799 and finally to Harrisburg in 1812. The current capitol, known as the Huston Capitol, is the third state capitol building built in Harrisburg. The first, the Hills Capitol, was destroyed in 1897 by a fire. The second, the Cobb Capitol, was left unfinished when funding was discontinued in 1899.
